BIMOTA

KB4 and KB4RC 2022, the return to the origins

Bimota also presented its new KB4 in the form of a concept during the Milan Salon of 2019, and also announced its “Vintage Inspired” version, the KB4-RC Cafe Racer style, from the versions of a misma moto, but conceptually different, and how es norm in the Italian house created with a different spirit than any other bike.

KB4 is the second motorbike that Bimota has presented in less than two years, after its new one it was marked by the association with Kawasaki, from which it will take its engines from now on. In its first creation of the Tesi H2, the motor unit of the supercharged model of the Japanese company was used, and in this second the one-liter tetracylinder that equip motorcycles like the Z1000 or the Ninja 1000 SX.

CLASSICAL INSPIRATION...The design of both motorcycles is inspired by the models of the brand from the 70s, but obviously all the mechanics are fully up-to-date, with an engine that offers 142 hp that is installed with the standard configuration of the original, so that it is fully valid. its approval, although it has some news, it is more evident in its refrigeration system.

Pier Luigi Marconi, the current top director of the company, started his career in Bimota by being the maker of the first Tesi, based on his project to end an engineering career, and later he also reads Benelli Tornado 900 planted as a model of superbike, which distinguished itself among other things for locating the water radiator on the back of the motorcycle.

UN TUNNEL...This peculiarity is likely to appear in the new Bimota KB4, which has the water radiator on the hill, installed in an inclined position below the seat of the pilot. As the four-cylinder in-line engine is sufficiently thick to prevent the creation of a conduit that carries the air through the center of the motorcycle, a pair of tunnels have been placed on the sides that conduct it forcibly from the front.

The design of the KB4 is due to the ingenuity Enrico Borghesan, who was able to move from the first pussy to the real-size model in just a few months, achieving a design really different than what others offer. In any case, in addition to their particular design, these Bimotas are characterized by having exclusive components.

BIMOTA CHARACTER...In addition to the use of top-notch components such as the 43 mm Öhlins FG NIX30 horquilla, the Misma damper supports the most exclusive Brembo brake system, the Bimota stands out for a chassis that combines a multitubular structure in it Front part with aluminum plates on the back and a tipper made in a similar way to those of competition motorcycles.

The usual structure of a tipper combines cast pieces with other tubular or stamped pieces, but the KB4 tipper is manufactured from an aluminum block that has been machined to achieve the desired shape, so that all possible unions between pieces are eliminated. It also includes the upper support of the shock absorber that is integrated into it.

OPTIONS...Sharing the mechanical base, the versions of the Bimota KB4 are distinguished by the presence of a complete careened no. The first recalls inevitably the design of its predecessors, KB1 1978, K2 1981 and KB3 1983, with its round headlight and its surrounding fairing, while the second stands out for the lateral ducts that lead to the air to the radiator, and that sounds more evident that en su hermana.

The motorcycles have some other differentiating details such as their leather seat, and their dimensions of both are quite contained, with a distance between axles that does not reach 1,400 mm and a steering geometry that is not radical as in the past. With the Bimora Tesi H2 in production, this second motorcycle from the Italian firm will start production next April.
